VISIBLE TANK FOR GASOLINE PUMPS.

Application filed June 11, 1919. Serial No. 303,442.

To all whom t may concern.'

Be it known that I, ARTHUR E. DAVEN- ron'r, a citizen of the United States, residing in Brooklyn, county of Kings and State of New York, have invented certain new and useful Improvements in Visiblev Tanks for Gasoline Pumps, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to apparatus for dispensing fluids and particularly to visible measuring tanks for gasoline pumps or similar devices for distributing motor fluid.

@ne object of my inventionr is to provide a measuring tank which shall have a pleasing appearance and other advantages of the cylindrical glass measuring tanks in use for this purpose hitherto, but which shall have the advantage of beingy largely formed of relatively thick wire-glass so that it will be capable of withstanding relatively heavy blows without danger of destruction.

Visible measuring tanks have hitherto been formed by usual glass blowing processes and consequently it has been considered impossible to utilize wire-glass in their formation. According to my invention, I provide a tank which has all the advantages of the visible blown glass tank, but which is composite, being comprised of certain metal sections with curved glass panels which are formed of wire-glass but which are assembled in such manner that when the measuring tank is mounted in a gasoline pump it has all the appearance of being a continuous cylindrical glass tank. My irnproved tank is formed so thatA there is no danger of leakage and has a still further advantage of being readily constructed of any suitable size desired, without having thin or easily frangible walls.

Other objects and advantages of my invention will be set forth hereinafter and I will now describe the same with reference to the drawings and point out the novel features thereof in the appended claims.

Referring to the drawings:

Figure 1 is a vertical elevation in crosssection taken on the line 1-1 of Figure 2.

Figure 2 is a sectional plan View taken on the line 2 2 of Figure 1.

Figure 3 is a partial elevation to illustrate certain details of the construction.

rIhe structure comprises a head 10 of metal, having an annular groove 11 formed therein nearl its edges, and a perforated flange 12 and a spaced ring 13 at the opposite end provided with an annular groove 14 corresponding to the groove 11 and a flange 15 corresponding to the ange 12.

This ring or collar has an inwardly extend?.

ing annular flange 16 forming a shoulder on which a plate glass disc 17 is mounted, a gasket 18 being interposed.

As clearly shown in Figure 2, a pair of sector-shaped wall sections 19 and' 2O are disposed at opposite sides and serve as rigid spacing members between the head 10 and the ring 13. rIhey extend into'the annular grooves 11 and 14 at their respective ends and they are provided with axially extending grooves 21 and 22 which are so formed as to receive wire-glass side panels 23 and 24. These panels also fit loosely into the grooves 11 and 14 as clearly shown'in Figure 1, and are sealed in place by a litharge, or some other suitable cementing material which is also utilized to seal all the joints of the tank. Litharge has the characterisic of not being attacked 0r dissolved by gaso- The longitudinal oints between the panels and the wall sections 19 and 2O are covered externally by a plurality of strips 25 which are secured by screws 26 or other suitable means to the head 10 at one end and the ring 13 at the opposite end.

The head 10 and the ring 13 are clamped together by tie rods 27 which extend through the flanges 12 and 15 and are screw threaded near their ends to receive clamping nuts 28.

The head 10 is formed with a depression 29 terminating in a drain outlet 30, and is, furthermore, provided with a central opening 31 through which an overflow pipe or tube 32 extends. This tube is clamped in position by nuts 33 and 34 as clearly shown in Figure 1. A liquid draw-olf pipe 35, which extends for a short distance above the bottom of the tank is secured in position by nuts 36 and 37 and provides a passage through which gasoline may be delivered to the customer.

The arrangement of pipes and the formation of the overflow form no part of my present invention and may be varied as desired.

Various structural modifications may be effected within the spirit and scope of my invention and I intend that only such limitations be imposed as are indicated in the appended claims.

What I claim is:

1. A visible measuring tank for dispensing liquids comprising a fluid-tight chamber having a metal head with an annular groove formed therein near its edge, a spaced ring or circular frame having a corresponding annular groove, and a plurality of cylindrically curved segments, some of which are glass, sealed into the grooves, and a glass top plate seated on the ring or frame.

2. A visible measuring tank for dispensing liquids comprising a fluid-tight chamber having a metal head with an annular groove 4formed therein near its edge, a spaced ring or circular frame having a corresponding annular groove, and a plurality of cylindrically curved segments, some of which are wire glass, sealed int-o the grooves, a glass top plate seated on the ring or frame, and longitudinal clamping bolts for drawing the ring toward the metal head.

3. A visible measuring tank for dispensing liquids, comprising a fluid-tight chamber having a head member provided with a groove adjacent its perimeter, a spaced upper member provided with a corresponding groove adjacent its perimeter, and a plurality of side walls or panels' seated and sealed in said grooves, the lateral edge of one of each pair of abutting panels being provided with an offset projection overlapping the edge of the adjacent panel, sealing material interposed between the edges of each set of abutting panels to provide a tight joint, and narrow retaining strips covering the several joints thus formed.

4. A visible measuring tank for dispensing liquids, comprising a fluid-tight cylindrical chamber having a pair of spaced heads of circular form provided with annular grooves adjacent their perimeters, a pair of oppositely disposed arcuate metal panels seated and sealed in said grooves and having offset projections, and a pair of oppositely disposed wire glass arcuate panels interposed between the metal panels and seated and sealed in said grooves with their lateral edges overlapping the offset projections of the adjacent metal panels, sealing material interposed between the adjacent abutting edges to form tight joints and narrow retaining strips secured to said heads and covering the several joints thus formed.

In witness whereof, I have hereunto set my hand this 7th day of June, 1919.

A. E. DAVENPORT.
